 If you need further assistance please read [How To Contribute](https://github.com/opencv/opencv/wiki/How_to_contribute).
 
+Please:
+
+* Read the documentation to test with the latest developer build.
+* Check if other person has already created the same issue to avoid duplicates. You can comment on it if there already is an issue.
+* Try to be as detailed as possible in your report.
+* Report only one problem per created issue.
